3． Peak Search

Set the peak search condition. The available options are Maximum and Para.

 If Max is selected, the system searches for the maximum on the trace.

 If Para is selected, the system searches for the peak that meets the

parameter condition on the trace.

Note: This setting applies only to the peak search executed by pressing Peak

at the front panel; while other searches such as Next Peak, Peak Right, Peak

Left and Min Search are all based on the Para.

Peak Table

Open the peak table (in the lower window) which lists the peaks (with frequency

and amplitude) that meet the peak search condition. Up to 10 peaks can be

displayed in the table.
